Since 1984, I have been a user at SLAC working in the MARK III, SLD, and BABAR experiments. I obtained my PhD from the University of Munich in 1984 working in the CUSB experiment at Cornell University. I was the first to observe four of the 3P states in the bottomonium system (cb1, cb2, cb1 cb2). Before my appointment as full professor at the University of Bergen in 1995, I worked at Caltech as a Lynen fellow, senior research fellow and Heisenberg professor. During my last years at Caltech I performed several analyses in the CLEO experiment (e.g. search for tmg, B K(*)l+l-, full angular analysis in B JyK*). From Bergen I lead a group working on Bs mixing in the DELPHI experiment. Concerning hardware my expertise lies in calorimetery and photon readout. Furthermore, I have built proportional chambers and repaired drift chambers. I have contributed to the BABAR experiment from the very beginning studying the readout of CsI crystals with various photodetectors  and performing R & D on aerogel threshold Cherenkov counters. In analysis I am involved mainly in radiative penguin decays. Concerning software, I have written several simulation and fitting programs from scratch.


In BABAR I served as convener of the radiative penguin analysis working group and was a member of the speaker's bureau. With minimal support from Norway I managed to attract students for BABAR. Up to now they completed two PhD theses and six master theses. This is an excellent outcome considering that in my fully supported projects (Delphi, ATLAS) two PhD students and three master students have completed their theses. Three former members of my group now work at SLAC in BABAR and the Fermi Gamma Ray Telescope. I am an active referee for PRL, NIM and the PDG.


In the following I focus on a few issues where I think SLUO can have a major impact in the next two-to-three years.





I think SLUO should support and push main interests from the SLAC/users community concerning new projects at the laboratory/DOE. One example is R & D for a

linear collider detector. Independent of the machine energy unsolved issues exist (like the concept of  particle flow) that need to be addressed experimentally

before a decision of the detector design is made. Another example is the SuperB factory. I think that this machine can only be built successfully, if it gets the full

support of SLAC machine physicists both in the design and in the construction. If this effort fails to allocate new resources from the government, I would investigate

in the possibilities of attaining private funding.


In the past SLUO has been involved in helping with the organization of meetings and workshops at SLAC. Since this has been a fruitful enterprise (I know from

meetings/workshops I attended) I would propose to continue this effort.


If elected I will take responsibility for one of these issues. Personally, I favor issues under the first two bullets, but I think this should be discussed and decided among the SLUO members.
